I Beitlmown'that-I,5-W1Lms A. INGALLS, a subject'of-Geor'ge the :"Fifth, King of Eng-. land, 'residingizin Cleveland;v (Juyahoga v county, Ohio, have invented certain new. and useful Improvements .Kni-tting-Machines;

' and I'hereby "declare the following to be a full, clear, and exact description ofthe same, such as will enable others skilled inthe art. to which it appertains to'make and to use the same. if

a-My inventionnrelates yarnguide for,

knitting 'machinesand its object, in addition to guiding'thethread: and opening the latch ofathei'needl'etas is customary in the ordi- E nary: form of-yarn guide, is to produce a 1 form of yarn guid-win'wvhi-ch' the guide properhnd-the'latch lifting point :can be readily and independently? adjusted-toany i desired position'and also to prevent damage to-thefineedl'es in riding over the'latch openling "point." These objects I accomplish by dividing the yarn. gu'ideinto tw'o separate parts eachwsepara'tely attached to the machine i-ir such niahner that it'may be freely" adjusted. To overcome the lessor breaking of needles whenfthe iieedle rides over the latch lifting point, that part'ofthe fyarh guide carrying the lifting orzopening'point is separated from the second part'-o1 yarn guide proper by sufiicient space to permit the needle 1 a1 llin back into place and-"- theifoi' roper is? so ward end of the yarn guide formed as to force the needle ack into its ordinary path in the event it should be so sprung or otherwise damaged as not to fall back in the ordinary course.

In the accompanying drawings I show the invention in the form adapted to be used on a plate and cylinder machine.

Figure 1 is a plan view of the device showing a section of the needle plate, a section of the cam plate and showing the position of the yarn guidewith the supports shown in dotted lines. Fig. 2 is a. side elevation of the yarn guide proper with end view of the adjustable holder. 3 is a side elevation of the latch opening evice showing the latch opening point and means for holding and adjusting the same. Fig. 4 is a bottom view of the yarn guide proper and Fig. 5 is a bottom view of the latch opening device. Fig. 6 is a side elevation of the holding block to be mounted on the cam plate and of the open end of the yarn guide proper and the adjustend elevation on line able'holder therefor. Fig.-7 is a sectional X, X, Fig. 6.

A isthe needle plate of the machine and a the needles mounted therein in the usual manner.

B is the cam plate. I

-C and D are holding blocks attached to theoa'r'n late by the screws 0 c, (1, (F.

E is a older having its stem e adjustably mounted in the block C and having its head bored to receive the stem G and is provided with a set screw E for holdin the stem G. Secured to 'thelower end of t e stem G is theneedle evener I and on the upper side of the'latteris mounted the adjustable latch lifter K which is secured to the needle evener I by the. screw 10 -The latch opening point is is adjusted to the desired position by means of 'the'screws is, k and In. The stem f of the holder F is mounted in a holding block D inthe manner shown in Fig. 7. The stem H of the yarn guide J is mounted in. the head of the holder F and secured in the desired position by the set screw F The blocks 0 and D are mounted on the cam plateBwin approximately the desired position. To permit adjustment the holes 0 and D through which the screws 0 (1 pass are of larger diameter than the screws, permitting theinner endof the blocks to be shifted in either direction as may be desired.

The stems-e and f of the holders E and F -mayzbe set to the desired position and there secured by the screws 0 and d. The needle evener I and thread guide J may be adjusted vertically or may be turned on the stem G and H and secured in any desired position by the screws E and F In this manner it will be seen that the needle evener, the yarn guide and the latch lifting point can be accurately adjusted to and rigidly secured in any desired position.

In actual operation the parts are adjusted substantially to the ositions shown in the drawing Fig. 1 and igs. 2 and 3. It will be noted that with the parts. in the relative positions indicated, the latches of the needles are prevented from closing from the time they are opened by the point is until they have passed the rear end of the yarn guide J. The needle evener I passes under the inner end of the needles, the latter sliding slightly up the inclined surface 2' of the needle evener, bearing against the upper surface of the needle evener only sufficient to hold them in position to permit the point 70' to project underneath and raise the latch of the needle without coming in contact with the needle any needle so riding over the point would pass along the upper surface of the latch lifter K and then drop in, or be forced down, between the latch lifter and the yarn guide thereby preventing damage to the needle by preventing its coming in collision with the yarn guide.

Having described my invention, I claim:

1. In a knitting machine the combination of a latch opening point suitably attached to the machine with a yarn guide located immediately behind said opening, point and having its'forward end beveled on the under side to engage needles riding over the latch opening point and force them to their original position for the purpose set forth.

2. In a knitting machine the combination of an adjustable latch opening point, a yarn guide having its forward end beveled on the underside to engage needles riding over the latch opening point and force them downward and means for adjustably 'attaching said latch opening point and said yarn guide to the machine for the purpose set forth.

3. In a knitting machine the combination of an adjustable needle evener suitably mounted on the machine, a latch opening point mounted on said needle evener, and a yarn guide having its forward end beveled on the under side to engage needles riding over the latch opening point and force them downward for the purpose set forth.

4. In a knitting machine the combination of an adjustable needle evener suitably mounted on the machine, an adjustable latch opening point mounted on said needle evener, a yarn guide having its forward end beveled on the under side to engage needles riding over the latch opening point and force them downward for the purpose set forth. j I

5. In a knitting machine the yarn guide J with its stem H securedin the holder F, said holder being secured to the cam plate by the block D, screws in said holder. F and block D for adjusting the holder and the stem H in combination with the needle evener I with its stem G mounted in the holder E, said holder being secured to the cam plate by the block 0 and screws in said block C and holder E for adjusting said In the presence of E.
